Subject: Duplin County SR 1546 Bill Sutton Road Hurricane Pipe Replacement
WBS#: D1715403.2031127
(DWQ Permit Fee: $240)
Dear Mr. Shaver and Ms. Steenhuis:
The North Carolina Department of Transportation plans to replace replaced an existing 36" in
diameter by 48' in length CMP at location Lat: 35.079754, Long:-77.757002 on SR 1546 Bill
Sutton Road where it crosses a UT to Burn Coat Creek (C; Sw) approximately 0.09 miles W of SR
1547 Grady Smith Road. The proposed replacement structure is a 60" in diameter x 48' in length
CMP w/ HW. NCDOT would like to request a waiver from the depth specifications of the regional
conditions 3.6.1 of the Nationwide Permit 3 and the corresponding General Condition 11 of the
Water Quality General Certification No. 4132. Due to the existing geomorphologic fall of the
stream channel, burying both of the inverts of the new 60" CMP 1' below the natural streambed
elevation would result in a greater than 11 percent pipe slope, causing a high flow erodible
condition. NCDOT plans to bury the inlet l' and install the pipe on a 2% slope which would set the
outlet approximately 3.5 feet above the natural stream bed. Approximately 10 LF of riprap flume is
proposed to be placed back in the area of the existing riprap flume. (See Attached Permit Drawing).
By copy of this letter and enclosures, NCDOT is requesting issuance of Nationwide 3 approval
from the US Army Corps of Engineers and 401 Water Quality Certification (WQC) #4132
approval from the Division of Water Resources (DWR). A method of debiting $240 to process the
WQC request has been provided as noted in the subject line of this application.
If you have any questions or need any additional information, please contact me at [phone]
or at [e-mail].
Sincerely,
Sean Farrell

This product is generated from the USDA-NRCS certified data as
of the version date(s) listed below.
Soil Survey Area: Duplin County, North Carolina
Survey Area Data: Version 15, Sep 16, 2019
Soil map units are labeled (as space allows) for map scales
1:50,000 or larger.
Date(s) aerial images were photographed: Mar 7, 2015—Nov
28, 2018
The orthophoto or other base map on which the soil lines were
compiled and digitized probably differs from the background
imagery displayed on these maps. As a result, some minor
shifting of map unit boundaries may be evident.
